Description

Technical Field

[0001] This utility model relates to the field of cutting bed technology, specifically to a segmented air-suction cutting bed. Background Technology

[0002] Conventional cutting tables typically use a single, simultaneous air intake. As the cutting process continues, once the material (such as fabric) on the table has been cut, the table continues to maintain a single, continuous air intake state, which is unnecessary for the cut material. Therefore, this single-intake method suffers from high energy consumption and waste. While some segmented air intake cutting tables have been proposed to address this issue, existing cutting table structures are generally complex and have high manufacturing costs.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. The components of the embodiments of this utility model described and shown in the accompanying drawings can typically be arranged and designed in various different configurations.

[0025] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0026] In the description of the embodiments of this utility model, it should be noted that if terms such as "upper," "lower," "horizontal," or "inner" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this utility model. Furthermore, terms such as "first" and "second" are only used to distinguish descriptions and should not be construed as indicating or implying relative importance. In addition, the appearance of the term "horizontal" does not mean that the component is required to be absolutely horizontal, but rather that it can be slightly tilted. For example, "horizontal" simply means that its direction is more horizontal than "vertical," and does not mean that the structure must be completely horizontal, but rather that it can be slightly tilted.

[0027] In the description of the embodiments of this utility model, it should also be noted that, unless otherwise explicitly specified and limited, the terms "set," "install," "connect," and "link" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0028] The present invention will be further described below with reference to the accompanying drawings:

[0029] See Figures 1 to 8 This illustration shows an embodiment of the segmented suction cutting bed of this utility model, comprising a bed body 1, an adsorption table 2 with four cutting zones arranged sequentially from front to back on the upper part of the bed body 1, a cutting mechanism 3 on the upper part of the adsorption table 2 for cutting materials (such as fabric), and a segmented suction device 4 connected sequentially to the four cutting zones of the adsorption table 2 on the lower part of the bed body 1 for segmented suction of the adsorption table 2. It can be understood that the number of cutting zones on the adsorption table 2 can be increased or decreased according to actual needs. Figure 1 The dashed lines on the surface of the adsorption stage 2 represent the dividing lines of the cutting area.

[0030] Specifically, see Figures 5 to 8In the illustrated embodiment, the segmented air intake device 4 includes a bellows 401, which has an air outlet 402 and four air intakes 403. The bellows 401 has three perforated partitions 405 inside, which divide the inner cavity of the bellows 401 into four interconnected air chambers 406. The front side of each air chamber 406 is connected to an air intake 403 and the rear side is connected to a cylinder 404. The telescopic end of each cylinder 404 extends movably into the corresponding air chamber 406 and is connected to a cover plate 407 for opening or closing the air intake 403. The air outlet 402 is connected to one of the air chambers 406.

[0031] It can be understood that the number of air outlet 402, air inlet 403, cylinder 404, baffle 405, air chamber 406, and cover plate 407 can be increased or decreased according to actual needs; at the same time, the positions of air outlet 402, air inlet 403, cylinder 404, and baffle 405 can also be adjusted according to actual needs. In the illustration, only the air outlet 402 is shown on the right side of the bellows 401, the air inlet 403 is shown on the front side of the bellows 401, the cylinder 404 is shown on the rear side of the bellows 401, and the baffle 405 is shown horizontally spaced. In one embodiment, the air outlet 2 is located inside the bellows 401. However, depending on actual needs, the air outlet 2 can also be located on any side of the bellows 401 other than the right side, such as the left, upper, or lower side. Similarly, the air inlet 403 can also be located on any side of the bellows 401 other than the front side, such as the upper, lower, or rear side. The cylinder 404 can also be located on any side of the bellows 401 other than the rear side, such as the lower, upper, or rear side. The partition 405 can also be configured in any spacing form other than horizontal spacing, such as vertical spacing. It is important to note that the air inlet 403 and the cylinder 404 must be aligned front to back so that the cylinder 404 can move the cover 407 through its telescopic movement, thereby opening or closing the air inlet 403.

[0032] Specifically, in order to improve the sealing between the cover plate 6 and the air intake 3, as a further improvement to the above embodiment, see [reference needed]. Figure 7 and Figure 8 A sealing plate 408 is connected to the side of the cover plate 407 away from the cylinder 404. With the setting of the sealing plate 408, when the cover plate 407 blocks the air intake 403 under the push of the cylinder 404, a sealing connection can be formed between the sealing plate 407 and the inner wall of the air box around the air intake 403 to prevent gas leakage inside the air box.

[0033] Specifically, see Figure 2In the illustrated embodiment, the cutting mechanism 3 includes a crossbeam 310 disposed above the adsorption table 2, two drive mechanisms 320 disposed at the left and right ends of the crossbeam 310, and a cutting head 330 disposed at the upper end of the crossbeam 310.

[0034] More specifically, see Figure 4 In the illustrated embodiment, the drive mechanism 320 includes a first bracket 321, which is fixedly connected to the crossbeam 310. A first motor 322 and a first slider 323 are connected to the first bracket 321. The output end of the first motor 322 is connected to a first gear 324, which meshes with a first rack 5 disposed on the bed 1. The first slider 323 slides with a first slide rail 6 disposed on the bed 1.

[0035] More specifically, see Figure 2 In the illustrated embodiment, the cutting head 330 includes a second bracket 331, on which a cutting head 332, a second motor, and a second slider 333 are connected. The output end of the second motor is connected to a second gear, which meshes with a second rack 311 disposed on a crossbeam 310. The second slider 333 is slidably engaged with a second slide rail 312 disposed on a crossbeam 310.

[0036] More specifically, see Figure 3 In order to control the travel of the cutting head 330 on the crossbeam 310 and improve the reliability of the cutting head 330, in the illustrated embodiment, anti-collision blocks 313 are respectively provided at the left and right ends of the crossbeam 310.

[0037] Specifically, the segmented suction cutting bed provided by this utility model also includes a vacuum pump (not shown in the figure) connected to the segmented suction device 4 and multiple air ducts (not shown in the figure) connected to the segmented suction device 4 and the adsorption table 2; wherein, the vacuum pump and multiple air ducts are all located at the lower part of the bed body 1, one end of each air duct is connected to an air intake 403 of the segmented suction device 4, and the other end is connected to a cutting area of ​​the adsorption table 2. The vacuum pump is used for evacuation, and the air ducts are used to connect the segmented suction device 4 and the adsorption table 2. Under the evacuation action of the vacuum pump, the surface of the adsorption table 2 is made to generate suction, adsorbing the material (such as fabric) onto the surface of the adsorption table 2 so that the cutting mechanism 3 can cut it.

[0038] Specifically, see Figure 1 The segmented suction cutting bed provided by this utility model also includes a controller 7 disposed on the front side of the bed body 1. The controller 7 is electrically connected to the cutting mechanism 3, the segmented suction device 4 and the vacuum pump respectively, and is used to control the cutting mechanism 3, the segmented suction device 4 and the vacuum pump to perform corresponding actions.

[0039] The working principle of the segmented suction cutting bed provided in this embodiment of the present invention will be explained below by taking the example of the four suction ports 403 of the segmented suction device 4 corresponding one-to-one with the four cutting areas in the adsorption table 2:

[0040] In use, first lay the material (such as cloth) on the surface of the adsorption table 2, then start the vacuum pump and the first cylinder 404 in the segmented suction device 4 to work. The first suction port 403 is opened by the first cylinder 404, so that the first cutting area of ​​the adsorption table 2 generates suction. Then start the cutting mechanism 3 to move to the first cutting area and cut the material on the first cutting area.

[0041] After the material in the first cutting area is cut, the first air inlet 403 is closed by the first cylinder 404, at which point the first cutting area loses suction. At the same time, the second cylinder 404 is activated, and the first air inlet 403 is opened by the second cylinder 404, so that the second cutting area of ​​the adsorption table 2 generates suction. Then the cutting mechanism 3 is moved to the second cutting area to start cutting the material in the second cutting area.

[0042] After the material in the second cutting area is cut, the second suction port 403 is closed by the second cylinder 404, at which point the second cutting area loses suction. At the same time, the third cylinder 404 is activated, and the third suction port 403 is opened by the third cylinder 404, so that the third cutting area of ​​the adsorption table 2 generates suction. Then the cutting mechanism 3 is moved to the third cutting area to start cutting the material in the third cutting area.

[0043] After the material in the third cutting area is cut, the third suction port 403 is closed by the third cylinder 404, at which point the third cutting area loses suction. At the same time, the fourth cylinder 404 is activated, and the fourth suction port 403 is opened by the fourth cylinder 404, so that the fourth cutting area of ​​the adsorption table 2 generates suction. Then the cutting mechanism 3 is moved to the fourth cutting area to start cutting the material in the fourth cutting area.

[0044] After the material in the fourth cutting area is cut, the fourth suction port 403 is closed by the fourth cylinder 404, at which point the fourth cutting area loses suction. At the same time, the first cylinder 404 is activated, and the first suction port 403 is opened by the first cylinder 404, so that the first cutting area of ​​the adsorption table 2 generates suction. Then the cutting mechanism 3 is moved to the first cutting area to start cutting the material in the first cutting area.

[0045] By continuously cycling in this way, the four cutting areas of the adsorption table 2 can be cyclically drawn in segments. Under the premise that the total energy consumption of the vacuum pump remains unchanged, each cutting area of ​​the cutting mechanism 3 will be subjected to 4 times the adsorption force. Compared with the traditional whole-type air-drawing cutting bed, the segmented air-drawing cutting bed provided by this utility model can greatly improve the adsorption force of each cutting area on the cutting bed, and improve the precision and accuracy of material cutting.

[0046] Finally, it should be noted that the above description is only an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
